Destructive criticism and name calling: 

"How could you be so insensitive to that student?"

"You really went about that the wrong way."

"That's typical of your lousy attitude." 

Diagnosing or mind-reading:

"I know you just did that to annoy me."

"It's obvious you have a self-confidence problem. That's why you can't deal with rowdy kids." 

Ordering or threatening: 

"You'll do the copying and that's final!"

"I'm talking to the principal about your negative attitude."
